Pls refix your hardisk cables.After refixing it hardisk does not detect then hardisk has been faulty so it need to be replaced.

Windows was corrupted and it must be reinstalled. Use the recovery disk that came with the pc when you bought it.

The motherboard is not the problem.
Your hardisk is the problem.
See if your hardisk is detected during boot up procedure.
If it does... Run again your Windows XP CD installer and repair your operating system.
Having "Disk Boot Failure" error means the boot system of you operating system is corrupted.
If your hardisk is not detected... you better check if the power supply connector on your hardisk is secured and not loose..
If still not detected.. your hardisk crashed and need to be replace.

are you sure it is from the hard disk and not one of the cooling fans . you could check to see if it is screwed down properly.

insert your memory stick or your external drive / go to My Computer / right click your drive / go to properties / under the Security tab, just check the Full Control under permission / click apply then ok
hope this helps

Maybe your secondary hard drive is write protected due to third party software during the old installation of the system such as norton data recovery.

Hope this will be helpful to you.
